Electrical Safety Training

Electrical Safety Training

A qualified professional electrician must provide training. This training should be provided at least yearly to maintenance employees and others who may work on electrical systems.

This training should cover:

1. The skills and techniques necessary to distinguish exposed live parts from other parts of electrical equipment

2. The skills and techniques necessary to determine the normal voltage of exposed live parts.

3. The clearance distances and corresponding voltages to which a qualified person will be exposed.
Note: this is regarding a person working around live lines. The person may not approach or take any conductive objects without an approved insulating handle closer to exposed energized parts than shown in the following chart:
300V and less…avoid contact

Over 300V, not over 750V…. 1ft min. distance
Over 750V, not over 2kV…… 1 ft 6 in. min. distance

4. Safe Work Practices

a. De-energized parts – Live parts that operate less than 50 volts need not be de-energized
b. Energized parts – when and can you work on energized parts safely
c. Working on or near exposed de-energized parts – Lockout/tagout
d. Safely de-energizing components with stored energy
e. Stored non-electrical energy
f. Re-energizing equipment – safe practices
g. Working on or near energized parts
h. Work in a well lit area
i. Special precautions in a confined space – added PPE, etc…
j. The use of non-conductive portable ladders
k. Wearing non-conductive clothing and jewelry
l. Housekeeping
m. Interlock systems – only qualified persons may deactivate an electrical safety interlock for the purposes of working on a system

5. Working on portable electrical equipment

a. Proper handling – plug and cord
b. Visual inspection
c. Grounding type equipment
d. Conductive work locations – work in a dry area
e. Use of wet hands while working – bad practice

6. Working with circuit breakers

a. test equipment used – only qualified people may use them
b. why a breaker workers
c. general safe practices

7. Working around flammable materials
